I obviously didn't do my homework. I had a 5000 nex installed in my f150 using a harness that did not retain sync. This did not bother because the nex features overlap. The only problem is now my secondary display only shows the temperature and says dvd in the corner. Otherwise it is a dead screen. This drives me nuts. Other than tearing into my dash and replacing the harness is there any way to get any info, even a clock, to display on this screen. Any help would be extremely appreciated.
